I am using TsiLang version 6.4 and Delphi2009.
My application supports Russian language (Cyrillic) - the charset is set correctly. I can save the project to SIL file. This SIL file can be changed without problems - all Russian letters are displayed correctly.
Loading this changed SIL file again with TsiLangExpert destroys the Russian language - only cryptic signs are visible.
What is wrong here?

I've just installed version 6.4.1 - but the problem keeps the same.
Save the project from TsiLangExpert and load back destroys my Russian language. All other languages seems to be OK. Russian is the only language not using Latin characters in my project.

Yes, RUSSIAN_CHARSET is set for all entries in the column for Russian language.
The created SIL file can be loaded with SILEdior without problems. All Russian strings are displayed OK. Only loading a SIL file with the expert produces the wrongs characters.
